Watch: Your Taxes, As Fiscal Cliff Nears

While negotiations continued in Washington Saturday to try to stop a trip over the so-called fiscal cliff, millions of Americans face uncertainty about how to plan for the taxes that come due in April.

Most of the cliff's effects will be felt in 2013 and beyond, if there is no agreement to avoid tax increases and spending cuts.

That said, there are aspects of the cliff that make planning for the tax return due in April more complicated.

Some areas to consider: whether to claim capital gains now, your level of charitable giving, 401K plan contributions and other deferred income plans.
